Must-have mobile apps aside from FitDay
 

Aside from the FitDay app that we all use, what other apps do you want and should have? I'm a developer and I was thinking of creating my own mobile app but I thought it would be extremely helpful to first gain insight from people on what apps they want that are not yet existent today. If I create apps that are similar to already existing apps, I will just have lots of competition. But if I create an app that only I have, it would surely be a hit. So your input is really really welcome please. Thank you!

There are so many apps now a days and all of them have duplicates.

If you are interested in games, you should just make a new game. You cannot go wrong with them. One that I have not found yet, though, is an app that I can use for golf. That will be a cool app :)
